SPINNING AND TWISTING FRAME AND THE LIKE.

Application filed. July 12,

T 0 all whom it may concern:

Be it known that I, JOHN P. GAREY, a citizen of the United States, residing at El mira Heights, county of Chemung, and State of New York, have invented certain new and useful Improvements in Spinning and Twisting Frames and the like, of which the following is a specification.

My invention relates to spinning frames, twisting machines and the like and the object thereof is to provide simple and efflcient means for stopping the feeding of rovings through the drawing rolls after the thread or yarn has been broken. In connection with suchstop means 1 provide other improvements including an improved roving guide and means forlocking a series of the stop means or devices, the advantages of which will be understood from the description hereinafter given.

In the drawing Fig. 1 is a vertical section through a portion of a spinning frame embodying my invention; Fig. 2 a sectional plan on the line 2-2 of Fig. 1; Fig. 3 a section on the line 3-3 of Fig. 1; Fig. 4: a cross section through the train of rolls with the roving guide in section and the stop means in elevation; Fig. 5 an elevation of that part of the stop meansadjacent the roving; Fig. 6 a perspective of the severing or clamping member or plate and trigger alone; Fig. 7 an elevation of the roving guide; Fig. 8 an elevation of a modified form of roving guide; Fig. 9 a sectionof a portion of the twisting machine showing my invention applied thereto; Fig. 10 an elevation thereof; and Fig. 11 an elevationof the clamping device alone.

In the present instance I have shown my invention as applied to a spinning frame and will therefore describe the invention in connection therewith without restricting myself to that particular character of machine inasmuch as my invention is also applicable to what is known as a twisting machine.

The spinning frame may be and is shown as of the ordinary type, the same c0mprising suitable frame members including a board or table 1 on which are arranged a large number of spinning units in the usual manner. The spinning mechanism proper includes more particularly the usual draw ing rolls, the same located between the supply bobbin 2 and the spool 23. These rolls comprise three pairs of rolls 4, 5 and 6, re-

volved at progressively increasing speeds. The usual scavenger roll 7 cooperates with the rolls 66. One or more oft-he supply bobbins 2 may be used in connection with each set of rolls, although in the present in stance I have shown a single bobbin for the set of rolls.

The roving 8 is carried from the supply bobbin through the stop means hereinafter described, through a guide 9, through the drawing rolls, and thence through the eye or guide 10 located in the forward end of an arm forming a part of my stop means, and finally to the spool 3.

The'stop means comprises the stop proper and controlling devices therefor. The stop itself comprises a block 11 which is secured in suitable manner as by means of the bolt 12 to the horizontal bar 13. The severing or clamping device is made in the form shown in Fig. 6 according to which the plate proper marked 14L has a horizontal shaft 15 which bears in a horizontal opening in the block 11 with the result that the plate may be caused to move from its substantially vertical position and upon the roving and to engage and sever the roving by means of the opening 16 formed with converging and sharpened edges, to thereby grip the roving. This plate 14 is actuated by means of a trigger comprising a lever 17 pivoted at 18 in a vertical slot formed in the block 11 and having a forwardly eX- tending end adapted to engagethe central or cut-away portion of the shaft 15. When the lower arm of this trigger is moved to! the left (Fig. l) the plate la is rotated towards the right and then falls by its own gravity upon the roving as shown by the dotted lines in Fig. 4. It will be understood that this roving passes through a guide opening 19 in the upper end of the block 11.

Referring to the controlling devices for the stop proper, above described, the same comprises a series of arms and levers which are made adjustable with respect to each other and in sections so that one may pivot upon the other. As shown an arm 20 which carries the guide 10 at its outer end is detachably and adjustably secured in the outer end of a substantially horizontal but irregular shaped lever 21. This lever is pivoted at 22 at the upper end of a stationary bracket 23 and the forward end thereof is made in two sections which are pivoted upon each other at 2 1, so that the forward section and guide 10 may be moved upwardly without disturbing the remainder of the controlling devices. The lever 21 carries at its rear end an adjustable weight 25 for proper counterbalancing purposes. Near such rearward end of the lever 21 there is mounted, adjust-.

ably thereon, a vertical lever 26 having at its upper end a horizontal linger 27 at right angles thereto in whose path of movement the lower end of the trigger 17 extends.

Describing the operation of the stop means, and starting with the parts in their normal position shown in Fig. 1, the roving is now feeding from the supply bobbin to the spool. In the event that the thread or roving should break, the tension of the thread upon the guide 10 as it passes therethrough is relieved with. the result that the controlling levers are oscillated to the dotted line position shown in Fig. 1, these levers being so counterbalanced that they will move to this position when such thread tension is removed. As a result the finger 27 will operate the trigger 17 which in turn will operate the plate 1% and cause it to fall and clamp the roving whereupon the pull of the drawing rolls will sever the roving, so that-no more roving can be supplied to the drawing rolls upon which it would otherwise accumulate with destructive effect thereto. In rethreading, the plate l t is manually replaced to normal position, the severed roving is then threaded through the guide and rolls and through the guide 10 and then spliced to the broken end of the thread on the spool or bobbin. The tension of the thread in the guide 10 will carry the controlling devices to their normal operative position. The construction of the trigger 17 is such that when these controlling levers are returned to normal. position, such trigger will yield without disturbing or upsetting the clamping means or plate 1%. Instead of the usual trumpet guide in the rear of the rolls I prefer to employ the special form of guide shown in detail in Fig. 7, the same comprising a plate 28 secured to the usual longitudinal reci )rocating bar 29 and having a guide slot 9.. The advantage of this form of guide is that it avoids the necessity of threading through a small opening as isthe ease with the usual trumpet guide. In Fig. 8 I have shown a modified construction according to which a slot 30 is formed in the upper side of the bar 29.

In connection with my stop means I employ means for sin'iultaneously locking a series of my stop means to prevent their operation. As shown, a series of locking plates 31 are located in position to be shifted longitudinally below the levers 21 at a point behind pivots 22 and the same are secured to a longitudinal bar 32 which may be moved by hand by means of the handle The bar 82 is also connected to a downthis particular construction,

wardly extending rod' 34 connected to a shifting rod 35 which is in turn connected to the belt shifter (not shown) of the machine. By actuating the arm 35 by a handle (not shown) a driving belt will be shifted from the loose pulley to the tight pulley or vice versa. In this operation the lever 34 will In Figs. 9,10 and 11, I have shown myv invention applied to a twisting machine. The parts corresponding to those hereinbefore described are similarly numbered. In the thread 8 passes through the inclined slot 36 of the block 11 and over the usual rolls 37 and 38 and thence to the twister not shown. The 7 thread extends over the grooved roll 39 which is attached to the depending arm of the lever 1O, pivoted at 41. This lever carries. at its inner end an adjustable weight 42, to whose upper end is adjustably secured an arm 13, movable in the path of the lower end of the trigger 17 of the clamp ing device. The operationis the same as in the foregoing instance, that is, the clamping device will be-operated when the thread breaks and the lever 40 and arm 13 and also the clamp 14: take the position shown in dotted lines in Fig. .9. i
